proceeding.
• PTFE tape may be useful for sealing threaded connections.
5. If required, connect an in-line mini oiler to the tool.
• A mini oiler helps to prolong the life of the air tool.
6. If a mini-oiler is not being used, run a few drops of oil through the tool
before use. It can be entered through the airline connector or via the hose
at the nearest connection to the air supply.
7. Ensure the trigger is NOT depressed when connecting the air line.
USING THE NEEDLE SCALER
1. Hold the tool with both hands and bring towards the work at an angle of
approx. 60-70
o
. With the airline pressure set to 90 psi (621bar), squeeze the
trigger and allow the needles to come into contact with the work.
2. Moving slowly across the work surface, proceed to remove scale, rust or
other contaminants taking care not to damage the surface. Regulate the
air supply pressure and locking groove setting to adjust the performance of
the tool.
3. Release the trigger to stop operation, noting that the tool may run briefly
after the trigger is released.
DISCONNECTING THE AIR SUPPLY
1. Do not disconnect the compressed air supply hose until the air supply has
been shut down or isolated at the shut off valve and the compressed air
expelled by running the tool until it stops.
2. Refer to the compressor instruction manual for the procedure to shut down
and release the compressed air.
3. Once the pressure has been released, disconnect the air supply hose from
the needle scaler.
